CONNECTING DEVICE Filed Feb. 18, 1929 A ttor ncy Patented Aug. 19, 1930 UNITED STATES PATENT OFFICE SAMUEL S. MATTHES, OF MANSFIELD, OHIO, ASSIGNOB. TO THE OHIO BRASS COMPANY, I OF MANSFIELD, OHIO, A CORPORATION OF NEW JERSEY v CONNECTING DEVICE Application filed February 18, 1929. Serial No. 340,723.

My invention relates to the art of con necting wires particularly electric conductors such'as trolley wires and connecting to such wires separably formed bodies as, for instance, terminal members. v

The object of my invention is to provide primarily a connector for conductors which shall be simple and strong and maintain the adjacent ends of the wires in a fixed relation.

Another object of my invention is to connect the wires without removing from the wires any of the metal thereof so as to reduce the cross section but to have an interlocked relation between the wires and their connector.

Another object of my invention is to provide splicers which can be used with trolley wires and maintain the exposed contact surface of the connected wires in aliuement and maintain them in a fixed relative relation.

My invention resides in the new and novel construction. combination and relation of the various parts herein described and shown in the accompanying drawing.

In the drawing Fig. 1 is a side view of my invention.

Fig. 2 is an end view.

' Fig 3 is an enla 33 of Fig. 1. i

Fig. 4: is a longitudinal View of the lower surface of one form of my splicer shown in F ig. 1 for a limited length thereof.

Fig. 5 is a view showing the splicer in position between the aws of a means for locking the splicer securely to wlres and further shows a plurality of interlocking means between the splicer and wires and two of-such means before interlocking and two after interlocking.

Fig. 6 is a sectional view on the line 3-3 of Fig. 1 but with a trolley wire in position and mounted between the jaws of a compressing means for moving the interlocking pin to its interlocked relation with the trolley wire. 7

Fig.7 is an enlarged sectional view on the line 7-7 of Fig. 5 showing an interlock between the conductor, splicer and pin as completed.

Fig. 8 is a sectional view corresponding to rged section on the line that ofFig. 7 but for a conductor having a i uniformly circular cross section.

F ig. 9 represents a longitudinal section of the form shown in Fig. 8 taken on the line 99 but without the trolley wire and shows enlargements .in' the channel for the wire.

Fig. 10 is a sectional View ofa trolley wire shown in Fig. 5 beforeand after the wire has been locked in position.

The connecting of conductors, especially trolley wiresused in high speed operation of cars, is one of the important problems confronting an operator In my invention I provide a device which has the objects set forth above andwhich, while particularly adaptable to the connecting of trolley wires, either round or grooved types; lends itself'to the connecting of other forms of conductors or even for rods which may be used for other groove is employed as in Fig. 3'for a grooved conductor I provide-oppositely disposed and.

inwardly projecting lips 3 which are seated in the side grooves of the conductor. Transversely mounted in the body member are a plurality of pins 4 formedpreferably of steel.

Each pin is positionedin a tubularpassage 5 and is 'formedto lit the pin 4 s'ufiiciently snug to retain the pins and body member as a unitary device, which is a matter of extreme convenience tothe-user of the splicer.

The pin 4: is preferably formed. of a solid cylindrical rod having an elongated portion 6, having at the inner end'a reduced portion 7 formed with sides-8 which are parallel or substantially parallel to the sides of the portion 6. The portion 7 is adapted to be forced into and interlocked with the trolley. conductor 9. The upper or exposed end of the pin 4 has a reduced tapered portion 10 and a still more'tapered and pointed portion 11.

position with a smooth, straight, uninterrupted, exposed surface and in which the trolley wire will not move out of interlocked relation with the pins, due to the end 7 of the pins having substantially straight and par allel sides.

I claim 1. A wire splicer comprising an elongated body member, an open edge groove along one edge of the body to receive wires from both ends and inwardly projecting means to prevent the wires being displaced transversely of the groove and a plurality of means slidably mounted in the body member and movable transversely of the axis of the wires to interlock with the wires to prevent its moving longitudinally in the groove.

2. A wire splicer comprising an elongated body member, a groove to receive wires from both ends and means to prevent the wires being displaced transversely of the groove and a plurality of means slidably mounted in the body member and movable transversely of the axis of the wires to interlock with the wires below the surface thereof to prevent them moving longitudinally in the groove.

3. A wire splice comprising an elongated body member, wire receiving means, a pair of longitudinally alined wires having depressions below the wire surface and a plurality of means slidably mounted in the body member and movable transversely of the axis of the wire to interlock with the wire depressions to prevent its moving longitudinally in the passage.

4. A wire splicer comprising an elongated body member, wire receiving means for the wires to be spliced, a plurality of slidably mounted holding means movable transversely of the wire axis to interlock with the wires to prevent longitudinal movement and bentover means to prevent movement of the holding means to release the wires.

5. A wire splicer comprising an elongated body member, an open slot along an edge of the body to receive wires, a plurality of slidably mounted pins mounted in passages having axes transverse to and opening into the wire receiving axes and having ends adapted to enter pockets formed in the wire and opening at the surface.

6. A wire splicer comprising an elongate body member, receiving means for wires, a

plurality of passages having axes transverse to the wire receiving means and pins slidably movable in the passages and having ends with substantially parallel sides to project at one end into the wire receiving means and means on the body to engage the other end of the pin to prevent movement in the opposite direction.

7. A wire splicer comprising a body member, receiving means for wires, a plural ty of tubular passages opening into the receiving passage, the receiving passage having sepathe wires into the enlargements.

8. A wire splicer comprising a body member, an open slotalong an edge of the body to receive wires, a plurality of tubular passages opening into the receiving passage, the receiving passage having oppositely inwardly'projecting means to retain the wires against transverse displacement and enlargements adjacent the openings of the tubular passages on opposite sides of the axis of the tubular passages, and means mounted in the tubular passages to be moved into interlocking engagement with the wires andforce the displaced metal of the wires into the enlargements and means to hold the movable means in locked position with the wires.

9. A wire splicer'comprising an elongated body member having an open groove along one edge with inwardly projecting and oppositely disposed lips to engage grooves in wires positioned in the open groove, a plurality of tubular passages opening into the open groove, the grooves having enlargements mounted in the tubular passages to be moved into interlocking engagement with the wires and force the displaced metal of the wires into the enlargements and means to hold the wires.

10. A wire splicer comprising a body member to receive the wires to be spliced with a portion of the longitudinal surface exposed and pins movable in a transverse direction only to the axis of the wires to interlock with the surface of the wires opposite the exposed surface.

11. A wire splicer comprising a body member to receive the wires to be spliced, and pins movable in a transverse direction only to the axis of the wires to interlock with the wires and means'on the-pins to be engaged with means on the body member simultaneously with the movement of the pins to lock the pins in engagement with the wires.

12. The combination of a wire, a body positioned on the wire by a relative longitudinal movement and held against relative transverse movement and a pin slidable in the body with a single movement towards the side face of the wire to enter the wire for a limited distance thereof and form its own recess in the wire, the pin having a reduced end with substantially parallel sides to take the longitudinal strain off the wire at substantially right angles to the sides of the reduced pin end.
